Hey, BM.
There's a cover at the back of the engine (or so, I've read...I've never had a LS apart, or seen the back of one...). The cover, covers up on e or two oil passages, which obviously have the potential to leak. On LS forums I've read, GM came up with an improved cover (this was likely years ago, newest pasts are likely ALL improved).

I'd replace or regasket that cover while the trans in out. I'd replace the rear main also, just because the trans is out..There's sensors and such in the vicinity of the back of the engine that will be easy to get to while trans is out. Mostly just "O" rings.
